Energy and sustainability are key priorities in developing electric vehicle charging infrastructure, particularly to reduce carbon emissions and save operational costs. Solar Power Plants (PLTS) offer a potential renewable energy solution, although they still face challenges such as fluctuating efficiency due to weather changes and high initial investment costs. This study aims to analyze the efficiency and performance of Solar-Powered Electric Vehicle Charging Stations (SPKL) at Jakarta Global University (JGU). Measurements were taken on the voltage, current, and electrical power generated by the solar panels, which are transmitted to the Maximum Power Point Tracking (MPPT) system to charge electric vehicle batteries. Economic analysis was conducted using the Payback Period (PBP), Net Present Value (NPV), and Internal Rate of Return (IRR) methods. The results showed that the average MPPT efficiency was 61.47%, with fluctuations due to variations in sunlight intensity. Nevertheless, the PLTS system was able to generate sufficient power to charge electric vehicle batteries, although its performance slightly decreased during cloudy weather. Additionally, the use of PLTS provided annual operational cost savings of Rp 87,357.21 compared to conventional electricity from PLN. However, in terms of economic feasibility, the PBP calculation indicated a 20-year payback period. Furthermore, the NPV calculated at -Rp 4,118,596.8 and an IRR of -0.47% indicated that the project is not yet financially viable within a 20-year period. Despite this, PLTS still offers significant environmental benefits, and system optimization and the development of more efficient battery technology are needed to improve long-term performance and the economic viability of this project.
